12v. charger for MacBook Pro?

Does Apple--or anyone else--make a 12v. charger for the MacBook Pro? I want to use my MBP on an extended boat trip, and will need to charge it from the boat's 12-volt system. Haven't yet found a suitable charger. (Apple makes a cable to enable running the MBP on commercial airliners, but it does not charge the battery--it only supplies operating power.)

Thanks for any suggestions.

If you don't find a 12V charger, consider getting an inverter which will take the 12V and convert it to standard AC so you can use your usual charger. They aren't that expensive.

Thanks, Charlie, but I gave up too soon. Found this at Amazon:

Exactly what I need.

Still not certain about charging a MacBook Pro 13 with a 12-volt charger. This is the charger I found at Amazon:

When it arrived, I learned it is rated at 85 watts.

Now the factory-supplied Apple 120 v. charger for the 15" and 17" MacBook Pro is rated at 85 watts, but the factory charger for the 13" Pro is rated at 60 watts.

Am I likely to damage my MBP 13 with the 12v. 85 watt charger?

Thanks in advance.

Lopezian, the manufacturer also sells a version of that adapter rated for 60 watts; they can be readily found via your favorite search engine.

No. Your MBP will only draw as much power from the adapter as it needs.

Thanks, everyone. I've returned the 85w. charger and found a 60w. charger for MacBook Pro 13" at Other World Computing--a fine source of mac stuff.

Thanks again.
